Abstract (en)

[origin: WO9404601A1] There is disclosed herein a process for preparing an oriented polyethylene terephthalate article, by (a) surface treating the article to obtain good adhesive bonding by increasing the concentration of surface polar groups, and then (b) contacting the treated surface with suitable solvent that preserves the good adhesive bonding characteristics but removes undesirable blocking characteristics.
